HPE Ezmeral Data Fabric 6.2 Documentation
  • 6.2 Administration

    This section describes how to manage the nodes and services that make up a cluster.

    • Administering Users and Clusters

      Lists topics that help manage a data-fabric cluster.

    • Administering Nodes

      Provides a synopsis of managing nodes in a cluster.

    • Administering Volumes

      This section provide information about how to organize and manage data using volumes, a unique feature of HPE Ezmeral Data Fabric clusters.

    • Administering Files and Directories

    • Administering Tables

      Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.

    • Administering Streams
    • Administering Data Fabric Gateways

      A data-fabric gateway mediates one-way communication between a source data-fabric cluster and a destination cluster. You can replicate HPE Ezmeral Data Fabric Database tables (binary and JSON) and HPE Ezmeral Data Fabric Event Store streams. Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.

    • Administering Services
    • Monitoring the Cluster

      This section describes how to monitor the health and performance of a MapR cluster.

    • Configuring Security

      Describes how to configure MapR security and manage secure clusters.

    • Managing Secure Clusters

      Provides procedures that will enable you to use MapR clusters securely.

    • Administering the Data Access Gateway

      The HPE Ezmeral Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Ezmeral Data Fabric cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.

    • Planning for High Availability
    • Administrator's Reference

      This section contains in-depth reference information for the administrator.

      • maprcli and REST API Syntax

        This section provides information about the MapR command API. Most commands can be run on the command-line interface (CLI), or by making REST requests programmatically or in a browser.

      • Utilities

        Contains information about various scripts and utilities, that help setup, maintain, and monitor clusters.

      • Configuration Files

        This section contains reference information about various configuration files.

      • Alarms Reference

        The pages in this section provide details about all of the types of alarms.

        • User/Group Alarms
        • Cluster Alarms
        • Node Alarms
        • Table-Replication Alarms
          • Table Replication Errors

            Explains the alarm that is raised when there are table replication errors.

          • Table Replication Asynchronous

          • Elasticsearch Formatting Alarm

        • Secondary Index Alarms

        • Volume Alarms
      • MapR Environment

        This section provides information associated with the MapR environment.

    • Troubleshooting Cluster Administration

      Lists the common errors and their solutions.

    • Best Practices for Backing Up HPE Ezmeral Data Fabric Information

      Lists the best practices and performance considerations to follow when backing up HPE Ezmeral Data Fabric information.

Table-Replication Alarms

You can view table-replication alarms using the MapR Control System and the CLI. See Viewing Active Table Replication Alarms for more information.
